Answer:
10¹⁸ ergs
Step-by-step explanation:
From the question,
Using the expression
M = 
log(E/10¹³)................. Equation 1
Where M = Richter magnitude of earth quake, E = Energy released in ergs.
Given: M = 4.0
Substitute into equation 1 amd solve for E
4 = log(E/10¹³)
Log(E/10¹³) = (4×5)/4
Log(E/10¹³) = 5
E/10¹³ = 10⁵
E = 10⁵×10¹³
E = 10⁵⁺¹³
E = 10¹⁸ ergs
To find the scientific notation of a number, place a decimal point after the first digit. Count how many places you moved the decimal point and that will be the power of 10.
